app/Model/feed.php in MISP before 2.4.124 allows administrators to choose arbitrary files that should be ingested by MISP. This does not cause a leak of the full contents of a file, but does cause a leaks of strings that match certain patterns. Among the data that can leak are passwords from database.php or GPG key passphrases from config.php.

MISP 2.4.122 has Persistent XSS in the sighting popover tool. This is related to app/View/Elements/Events/View/sighting_field.ctp.

MISP 2.4.122 has reflected XSS via unsanitized URL parameters. This is related to app/View/Users/statistics_orgs.ctp.

In MISP 2.4.102, an authenticated user can view sightings that they should not be eligible for. Exploiting this requires access to the event that has received the sighting. The issue affects instances with restrictive sighting settings (event only / sighting reported only).

In app/Controller/TagsController.php in MISP 2.4.118, users can bypass intended restrictions on tagging data.

MISP before 2.4.115 allows privilege escalation in certain situations. After updating to 2.4.115, escalation attempts are blocked by the __checkLoggedActions function with a "This could be an indication of an attempted privilege escalation on older vulnerable versions of MISP (<2.4.115)" message.

In app/webroot/js/event-graph.js in MISP 2.4.111, a stored XSS vulnerability exists in the event-graph view when a user toggles the event graph view. A malicious MISP event must be crafted in order to trigger the vulnerability.

app/Model/Server.php in MISP 2.4.109 allows remote command execution by a super administrator because the PHP file_exists function is used with user-controlled entries, and phar:// URLs trigger deserialization.

An issue was discovered in MISP 2.4.108. Organization admins could reset credentials for site admins (organization admins have the inherent ability to reset passwords for all of their organization's users). This, however, could be abused in a situation where the host organization of an instance creates organization admins. An organization admin could set a password manually for the site admin or simply use the API key of the site admin to impersonate them. The potential for abuse only occurs when the host organization creates lower-privilege organization admins instead of the usual site admins. Also, only organization admins of the same organization as the site admin could abuse this.

An issue was discovered in app/webroot/js/misp.js in MISP before 2.4.107. There is persistent XSS via image names in titles, as demonstrated by a screenshot.

An issue was discovered in app/View/Elements/Events/View/value_field.ctp in MISP before 2.4.107. There is persistent XSS via link type attributes with javascript:// links.

A persistent XSS issue was discovered in app/View/Helper/CommandHelper.php in MISP before 2.4.107. JavaScript can be included in the discussion interface, and can be triggered by clicking on the link.

In MISP before 2.4.105, the app/View/Layouts/default.ctp default layout template has a Reflected XSS vulnerability.

An issue was discovered in app/Model/Attribute.php in MISP before 2.4.89. There is a critical API integrity bug, potentially allowing users to delete attributes of other events. A crafted edit for an event (without attribute UUIDs but attribute IDs set) could overwrite an existing attribute.

In MISP before 2.4.89, app/View/Events/resolved_attributes.ctp has multiple XSS issues via a malicious MISP module.

In app/Controller/ServersController.php in MISP 2.4.87, a server setting permitted the override of a path variable on certain Red Hed Enterprise Linux and CentOS systems (where rh_shell_fix was enabled), and consequently allowed site admins to inject arbitrary OS commands. The impact is limited by the setting being only accessible to the site administrator.

An issue was discovered in MISP 2.4.9x before 2.4.99. In app/Model/Event.php (the STIX 1 import code), an unescaped filename string is used to construct a shell command. This vulnerability can be abused by a malicious authenticated user to execute arbitrary commands by tweaking the original filename of the STIX import.

An issue was discovered in app/Controller/UsersController.php in MISP 2.4.92. An adversary can bypass the brute-force protection by using a PUT HTTP method instead of a POST HTTP method in the login part, because this protection was only covering POST requests.

An issue was discovered in MISP 2.4.91. A vulnerability in app/View/Elements/eventattribute.ctp allows reflected XSS if a user clicks on a malicious link for an event view and then clicks on the deleted attributes quick filter.

app/webroot/js/misp.js in MISP 2.4.91 has a DOM based XSS with cortex type attributes.
